Abstract: A syringe for dispensing liquid materials to a substrate. In one embodiment, the syringe includes a barrel having a first end, a second end, and an interior reservoir. A piston is slidably disposed within the reservoir and is movable to increase or decrease a volume of the interior reservoir near the first end of the barrel. A first end of the piston has a hemispherically-shaped surface profile, with an elongated apex extending therefrom, to dispense liquid from the first end of the barrel when the piston is moved in a direction toward the first end.

Abstract: A dispensing assembly including a cartridge and a retainer. The cartridge includes a dispensing end and defines a reservoir for holding a liquid. The dispensing end includes a connector portion for receiving an end fitting with a rotational connection. The retainer includes a first open end and receives the cartridge such that the connector portion communicates with the first open end in a manner allowing connection of the end fitting. The retainer couples with the cartridge in a manner preventing relative rotation between the cartridge and the retainer.
